No copyright infringed. -Ya see, the mean old government, years ago, said all TV companies/stations(except for specialty cable channels) have to broadcast their signal to the air and never repealed that, due to ignorant hicks who don't have a cable cord in the wall. -When the Cable TV broadcast company came along, they initially could get the signal for free, to be able to make a few bucks by sending the signal outside of the antenna range or for people in shiathole apartments. -The TV station then demanded payment and the cable company threw a few bucks their ways.

Fast forward to now..... TV Stations: "WHAaaaaaaaaaaaaa, we want even more free money to be able to double dip!!!!!!" "Our profits are more important than providing actual quality programming." "WHAAaaaaaa, we hate allowing you to see our commercials for free, outside of our antenna area!!!"

/So, can't enforce copyright on a 'free to air, broadcast'//The only real criteria is: Have to provide the signal 'as-is' with no signal substitution(inserting your own shiathole commercials, like Canada illegally does to U.S. rebroadcasted TV signals).
